The long-term service temperature of the zirconium containing aluminum silicate ceramic fiber module should also be determined according to the specific service conditions. If the service environment is good, and there is no collision, vibration, reduction atmosphere and high-temperature iron oxide corrosion, the service temperature is 1200-1260 degrees.

Although the use temperature of zirconium aluminum silicate ceramic fiber module is high, its strength is insufficient, especially in the air flow scouring and corrosive atmosphere, the service life is not long. In recent years, some measures such as protective coatings have been taken, but the effect is poor. Therefore, it is not recommended to use in the field with relatively poor environment.

The use effect of aluminum silicate ceramic fiber module is still very significant. Taking the continuous heating furnace as an example, this product has the following advantages:

1. The energy saving effect is remarkable, and the heat loss is significantly reduced;

2. For the heating furnace, the ceramic fiber module structure can reduce the mold cost, shorten the construction period and save the construction cost.

3. The reduction of cooling water can effectively save the power and water resources of the water supply pump.

4. Reduce the energy consumption and reduce the emission of combustion pollutants of the heating furnace to reduce the environmental load.

First, let's popularize the two concepts.

The fire resistance of aluminum silicate ceramic fiber module refers to the critical point at which the fiber material transforms from solid state to liquid state, which is also called high-temperature anti melting temperature or high-temperature anti softening temperature.

The service temperature of the aluminum silicate ceramic fiber module is determined by the shrinkage rate of the fiber, the crystallization amount of the fiber and the grain size of the fiber at a certain temperature.

In practical application, the material should be selected according to the service temperature rather than the fire resistance.

In addition to being used as a finished product, ceramic fiber can also be added to other refractory products as an auxiliary material, which can not only improve the fire resistance of products, but also reduce the thermal conductivity of products and increase the thermal shock resistance of products.
